AUTOMATIC STORM-BASH ADJUSTER AND FASTER. I

To all whom it may concern Be it known that I, NrLs EDWARD LIN- srRoM, a citizen of the United States, 're-- Adjuster and Fastener, of which the following is a specification.

My invention relates to an on nal auto-v matic storm sash adjuster and astener, in which an inclined rod bracket fastened to the storm sash operates in conjunction with a bracket fastened to either theupper or lower sash of the window proper.

The objects of my invention are: first, to provide an automatic opening and. closing device for the storm sash; second, to provide an automatic adjustment ofsize of opening of storm sash in proportionto the size of opening of the sash proper as it is raised or lowered; third, to provide an automatic fastener for the storm sash to hold the storm sash securely closed or at .any angle of opening; fourth, to provide for leverage and the reducing of friction in opening and closing the sash; fifth, to provide for convenience in attaching and de: taching the storm sash.

I attain these objects by the mechanism illustrated in the' accompanying drawing, in which- Figure I is a vertical view of the side of the storm sash and the sash roper, showing all sash closed. Figure F1 is a, vertical view of the side of the storm sash and the sash proper, showing the storm sash and the upper sash .of the sash proper open. Figure I and Figure II show the mecha-' nism used in conjunction with the upper sash of the sash proper.

Figure III is a vertical view of the side of the storm sash and the sash proper,-show- V is a detailed view of the bracket lpeciflcation of Letters Patent. Patented Mar. 28, 1922- Application filed January 2, 1m, Serial no. 848,921. Renewed February a, 1922. Serial 1: 584,825.

consists of two brackets; bracket 4 is at tached to storm sash 3 by means of screws.

Bracket 5 is attachedto sash proper 1 or 2 as desired. Bracket 5 is fitted with two grooved 7. Upon removal of pin 8, bracket 4 may be disengaged from bracket 5 and storm sash removed. Bracket 5 is provided with the sliding movement ofbracket arm 4 may be. accompanied with as little friction as possible. When force is applied to upper sash 1 of the sash proper. downwardly directed bracket 5 presses downward on inclined bracket 4, allowing sliding movement of the arm of bracket 4 and graduthe anti-friction rollers 6 and 7 so that ally forcing storm sash 3 outward. When force is applied upward on upper sash 1 of sash proper the reverse action" takes place, drawing storm sash 3 inward. 1 The locking of upper sash 1 of sash pro er automatically locksstorm sash 3. yfinvention allows an opening of any angle or size between positions of the sash shown in Figure-I and Figure II and Figure III and Figure IV respectively.

The angleof bracket 4 may be increased or decreased according to leverage power desired.

The bracket 4 may be inverted at a lower position on storm sash 3 and operated with bracket 5 also inverted and fastened at right angles on lower sash 2 of the. sash proper as shown in Figure III and Figure IV. Operation of lower sash' 2 of proper automatically operates storm sash 3 as hereinbefore indicated.

. To secure rigidity and proper'action, my invention provides for similar mechanism on both sides of window sash, thus requiring a similar mechanism on the opposite side of window, although for convenience only oneside of sash is herein described.

Storm sash 3 is attached to window frame 9 by means of binge 10 which allows swin ing movement of storm sash 3 as indicate l.

a certain use for my invention, I wish it to be understood that I do not wish to be limited to the use illustrated. Upon certain changes not affecting the principle of the mechanism as' described, it may be applied to various other uses.

While I have described and illustrated I claim- The combination, in a storm sash adjuster and fastener, of an inclined arm bracket fastened to the storm sash with bracket fitted with grooved anti-friction rollers and fastened to window sash proper, said first named bracket being slidably received between said rollers, whereby locking said sash proper locks said storm sash, and

opening or closing movement of said sash 10 proper imparts corresponding movement to said storm sash.

In testimony whereof I afiix my signature in the presence of two witnesses.
